Atlantic Technology IWTS-4 LCR Operating manual

“Entry-level” doesn’t apply

to its sound.

The Atlantic Technology IWTS-4 LCR is our lowest-

priced in-wall speaker but it borrows much of its

technology and simplicity of installation from its more

costly brethren.

This speaker uses a 6 ½” GLH (Graphite-Loaded

Homopolymer) woofer for solid bass down to 57 Hz

and Atlantic’s renowned 1” soft-dome Low Resonance

Tweeter (LRT™). Because of its low crossover point,

this remarkable tweeter allows the IWTS-4 LCR

to deliver much wider midrange dispersion than

conventional in-wall speakers for greater placement

ﬂexibility, without the severe acoustic and mechanical

drawbacks of the so-called “pivoting tweeter.”

Here’s why: The woofer in conventional in-wall

speakers handles too much of the midrange and

woofers send out the midrange like a ﬂashlight beam—

pretty much only straight ahead, with very little sound

side-to-side or up-and-down. So even if these speakers

have a pivoting tweeter, that doesn’t really help, since

it’s the woofer, not the tweeter, that handles the

directionally-critical midrange frequencies.

What’s needed is a speaker where the tweeter, not the

woofer, handles more of the midrange, because unlike

woofers, tweeters spread their sound out over a very

wide area.

Because of this, Atlantic has engineered an extremely sophisticated, high-performance

tweeter (the Low Resonance Tweeter, or LRT™) for the IWTS-4 LCR, and it can play

most of the middle tones as well, thereby relieving the woofer of having to do what

woofers can’t do. Our LRT tweeter spreads out the midrange sound over a much wider

angle than the woofer, so the IWTS-4 covers the entire listening area beautifully in

both the midrange and treble, even when it’s mounted high up on the wall. This tweeter

technology was originally developed for our In-Wall Closed Box series (retailing for up to

$1000 ea.), but is now available in the IWTS-4 LCR, at a fraction of the price. We know

of no similarly-priced in-wall speaker that can match its performance.

The IWTS-4 LCR uses a separate bafﬂe/frame installation assembly, so the frame

and grille can be installed ﬁrst and painted to match the room at the time the walls

are being painted. The speaker bafﬂe simply screws into the frame at a later date.

Very convenient.

A 3-position High Frequency switch located on the bafﬂe lets the user tailor the

speaker’s sound to the room’s acoustics, or to adjust the HF balance for personal

taste. For the perfect ﬁnishing touch, the IWTS-4 LCR incorporates an aluminum

tweeter faceplate with a precision horn, which optimizes the tweeter’s dispersion and

gives the speaker an unmistakably consistent family appearance in keeping with our

more expensive in-wall models.
